During the descent from the Rax, a skier injured her knee in the area of Siebenbrunner Wiese. The helicopter C3 has been requested, but was not able to perform the recovery due to the strong wind. Therefore a ground rescue was initiated with alarming of the local MRT of Mürzzuschlag and Reichenau. The C3 could later land in the lower area of the Siebenbrunner Wiese. The landlord of the nearby Waxriegelhaus and a member of our MRT tried to get to the injured person with a snowmobile, with success. After the first aid the injured person was taken to the waiting C3 with the snowmobile.
